If virDomainDiskDefFree(disk) is called in 'skipdisk:', then it's possible
to either return to skipdisk without reallocating a new disk (via the if
condition just prior) or to end the loop having deleted the disk. Since
virDomainDiskDefFree() does not pass by reference, disk isn't changed in
this context, thus the possible issue.
There were two warnings in this module
If the VIR_ALLOC_N(def->serials, 1) fails, then a virDomainChrDefFree(chr)
is called and we jump to cleanup which makes the same call. Just remove
the one after VIR_ALLOC_N()
In the label "skipnic:" a virDomainNetDefFree(net) is made; however, if
in going back to the top of the loop we jump back down to skipnic for any
reason, the call will attempt to free an already freed structure since
"net" was not passed by reference to virDomainNetDefFree(). Just set
net = NULL in skipnic: to resolve the issue.
Since '337a13628' - Coverity complains that 'net' is VIR_ALLOC()'d, but
on various 'cleanup' exit paths from the code there is no corresponding
cleanup.
XM and XL config are very similar. Disks are specified differently
in XL, but the old XM disk config is still supported by XL. XL also
supports new config like spice that was never supported by XM.
This patch moves all the common parsing and formatting functions to
the new file xen_common.c and adapts the XM parser/formatter accordingly.
This restructuring paves way for introducing an XL parser/formatter in
the future.
While moving the code, fixup whitespace, comments, and style issues.

Wrap formatting code common to xm and xl in xenFormatConfigCommon
and export it.

src/xenxs contains parsing/formating functions for the various xen
config formats, and is better named src/xenconfig.
